Lifetime spec for miniature all-in-one focus module and smart stage

“These precision micro-mechatronic devices have already proven their value in OEM products from handheld microscopes to industrial robotic vision systems,” said New Scale CEO David Henderson. “Now our ability to confirm this robust lifetime specification makes them an even easier choice for OEM engineers who need to embed small, smart, battery-powered motion mechanisms in their handheld and portable devices for commercial, medical and industrial applications.”

The lifetime specification is a 10x improvement for the M3-FS Focus Module and a new specification parameter for the M3-LS Linear Smart Stage. It is based on months of performance testing in which standard M3-FS modules achieved > 56 million movements of approximately 21 µm each for a total distance moved of 1.2 kilometers, with no performance reduction or sign of failure at teardown. Testing conditions included vertical motion and a 10g load. Actual lifetime will depend on the application and use case.

The M3-FS Focus Module was introduced in 2014 as a higher-performance alternative to the company’s original M3-F Focus Module. It incorporates improvements, such as harder-grade steel in the internal SQUIGGLE motor, that contribute to the longer lifetime. The M3-LS Smart Stage, also introduced in 2014, has the same improved materials and design.

New Scale’s M3 Micro-Mechatronic Modules incorporate piezoelectric motors, position sensors, bearings, drive electronics and embedded firmware into miniature housings with precision bearings, slides and other mechanisms. With only 3.3 VDC input and new longer lifetime specification, the modules are ideal for integration into handheld and portable instruments.
